摘要
通过对石窑店煤矿首采215205综采工作面支架压力进行实时观测,分析得出了该浅埋深工作面的来压步距、动载系数等顶板来压特征;从时间加权平均工作阻力、支架工作阻力分布频率等几方面分析了ZY10000/20/38D支架适应性,研究成果为类似地质条件下工作面支架选型和安全生产提供指导。
With the real time observation conducted on the pressures of the powered supports in No.215205 fully mechanized coal mining face-first coal mining face of Shiyaodian Mine,the paper analyzed the roof weighting distance,dynamic load coefficient and other roof weighting features of the coal mining face in a shallow depth seam.From the time weighted average working resistance,the working resistance distributed frequency of the powered supports and others,the paper analyzed the suitability of ZY10000/20/38D powered support.The study results could provide guidance to the powered support selection of the mining face and safety production under the similar geological conditions.
